    Moderate to strong SW winds continue to redistribute recent storm snow at treeline and in the alpine. Additional snow on Saturday night will contribute to slab development.

  • Deep Persistent Slabs

    This facetted weak layer is most easily detected in shallow snowpack areas at tree line and above. Steep rocky alpine faces still seem to produce avalanches on this layer although these observations are infrequent.
